What Is U-47700?

U-47700 is a synthetic opioid that is 7.5 – 8 times more potent than Morphine. In 2016, the DEA classified it as a Schedule 1 narcotic. It has had no medical use in the United States. It was originally developed by the pharmaceutical company Upjohn in the 1970s. It started emerging in 2014. It is also known as “pink,” “pinky,” and “pink heroin.”

Where Do People Get It?

U-47700 sold on the internet as a research chemical, it’s also sold on the street. It’s often pressed into pills and made to look like prescription Oxy IR, often combined with heroin or fentanyl.

What Makes It So Dangerous?

Research suggests that U-47700 has enhanced brain penetration, it’s more attracted to lipids than Morphine, which makes for a longer half-life (researchers think around 6.5 hours). It has been found in many counterfeit oxycodone tablets and is a key ingredient in “gray death.” There have been many overdose fatalities, contributed to Prince’s overdose and subsequent death. It is unable to be detected on most UDS screens, but LabCorp does have a test for it.
